Fixed my issue with 2 sets of Tmobile boosters

This simple app helped me fix issues I was having with 2 sets of boosters from Tmobile. The issue was that the boosters were defaulting to band 2 over band 12 or 4 and would not release it even after multiple resets. The first unit I thought the booster was defective because first power up it had 4-5 bars then boom down to one and LTE dropped off. Multiple resets and no change. I sent it back to Tmobile and they sent another. Same result I turned it in 5 bars I smile wait 5 min and jumps to one bar and my frustration starts. I thought it was defective as well. I called my networking friend and he said download this app and see if band 2 is checked! By simply downloading this app going to my coverage unit opening the app clicking the booster settings tab and I checking band 2 was all it took. It took me 1 min to fix the issue I was having for 6 weeks. This app also shows some basic networking statistics as well for you. It may not have every option a technician needs but it suited my needs nicely and by the way it was FREE. Thank you for this app!!!

Lazy Programming!

I am considering the purchase of this booster for my RV. I do all device admin on my iPad because it allows me to use a full-size keyboard.
So I downloaded this app to find out how it looks and feels and immediately learned something that may kill the plan to buy the booster.
Namely, the app works in portrait mode, only. This makes it impossible to use a keyboard.
If the app programer would have used common sense, they could have made provisions for landscape mode from the get go.
But, they did not. Too bad.

In the middle

It helps with signal that's for sure,BUT everything is limited. Settings are very restricted,poor support,2000's app design and 90's functionality. One in a decade node updates. Overlapping with 5Ghz bands with router. I want to see more flexibility and settings. Like I want to set specific WiFi band and more flexibility with settings overall.

Until the major overhaul 2 stars.
